Abstract (en)
[origin: US2012242009A1] The present invention relates to a method of producing color change in a substrate. The substrate includes an activatable colorant and a region that is heated prior to activating the activatable colorant. The substrate is exposed to electromagnetic radiation producing a first activated color region in the heated region and a second activated color region in a non heated region. The first activated color region appears in a different shade than the second activated color region.
